I’m trying to use NVEncode in motion estimate mode only. I updated sample app to support pngs and I’m getting quite weird results. What am I missing?
I’m calculating motion vectors from 2 pictures of moving circle:
magick -verbose -size 1024x1024 xc:skyblue -fill red -draw "circle 300, 300,350,350" box1.png
and second image (circle moved right by 10px):
magick -verbose -size 1024x1024 xc:skyblue -fill red -draw "circle 310, 300,360,350" box2.png
and I’m getting motion vectors like this (red means non zero motion vector at that point, light green no movement):
Somehow motion vectors gets repeated vertically. I tried with video, with other images and I get this kind of picture all the time. In this example red fills until bottom, but in more complex example it fills until next movement is found.
